A TUBULAR STRUCTURE IN ENDOTHELIAL CELLS AND PERICYTES OF HUMAN CAPILLARIES

[摘要] A tubular structure is described as occurring in large numbers in both the endothelial cells and pericytes of normal human capillaries. It is similar to that body found in the endothelial cells of small arteries in the lung of man and rat as well as in the skin vessels of the Ambyl-stoma. The morphologic characteristics of this structure are outlined.
